Iziphene eziqhelekileyo kunye nokuthintela umbhobho odibeneyo

Iziphene eziveliswayo kwimveliso eyiyo yemibhobho edityanisiweyo ye-high-frequency (astm a53 grade b erw pipe) ngamanye amaxesha ayibangelwa sisizathu esinye, kodwa idla ngokuba sisiphumo sokudityaniswa kwezinto ezininzi.Iziphene ze-Welding nazo zingabangelwa ezinye izizathu ezingaphandle kwendawo ye-welding, ngoko ke izinto ezininzi kufuneka ziqwalaselwe ngokubanzi iziphene , Ingxaki inokusombululwa kuphela ngokuhlalutya ngokucokisekileyo izizathu.

Ukubandakanywa

Indlela yokuqulunqa iziphene zokubandakanywa kukuba i-oxide yensimbi ayigqithiswanga ngetsimbi etyhidiweyo, kodwa ifakwe kwi-welding surface.

Ezi oksidi zetsimbi zidla ngokubunjwa kumphezulu wentsimbi etyhidiweyo kwi-engile engu-V.Xa i-strip edge isondela kwisantya esisezantsi kunesantya sokunyibilika, kwaye isantya sokunyibilika siphezulu kunesantya sokukhupha isinyithi esinyibilikisiweyo, i-apex yokuvulwa kwe-V-shaped iyakwenza isinyithi esityhidiweyo kwaye Ukufakwa kwee-oxide zetsimbi akunakuba ngokupheleleyo. ikhutshwe emva kwe-extrusion eqhelekileyo.Umphezulu wesisombululo setsimbi esicocekileyo sifakwe ezi oxide zetsimbi, ngaloo ndlela zenza iziphene kwinkqubo yokubumba kunye ne-welding.

Esi siphene siya kubangela ukuba i-weld ihlanjululwe emva kokutshatyalaliswa, kwaye ukufakwa kuya kubonakala kwi-fracture ye-weld.Esi siphene sibakho ngeendlela ezahlukeneyo, ngamanye amaxesha singatshatanga, ngamanye amaxesha kwikhonkco.

Amanyathelo okuthintela iziphene ezibandakanyiweyo:

1. I-angle emile okwe-V ilawulwa ngokungqongqo ngaphakathi kwe-4 ~ 6
2. Ukulungiswa kweyunithi ukuqinisekisa ubude be-angle yokuvula ezinzileyo
3. Umlinganiselo we-Mn/Si kwi-chemical composition of the strip mkhulu kune-8:1
4. Ukunciphisa i-oxidation yendawo ye-welding

Ngaphambi kwe-arc

Olu hlobo lwesiphene alunelanga ukudibanisa okubangelwa yi-pre-arc.Ngokuqhelekileyo, i-burr okanye i-oxide isikali kunye nomhlwa kwi-edge ye-strip yenza ibhulorho phambi kwe-apex ye-angle ye-V, ebangela ukuba isiphaluka esifutshane sibangele ukuba i-current ixhume kwaye ivelise i-pre-arc phenomenon, kunye ne-short-circuit. ngoku utshintsha ulwalathiso lwangoku kwaye unciphisa Ubushushu kwikona ye-V buyancipha.

Iziphene ezibangelwa kukushukuma kwangoko, ukwaphuka kwenqwelomoya eqaqambileyo kunye necaba kunokubonwa ukusuka kwi-weld fracture, ngamanye amaxesha akukho strip edge burr okanye oxide scale, rust, njl., kodwa i-angle encinci ye-V okanye i-voltage ephezulu kakhulu iya kubangela kwangaphambili i-arc phenomenon , Oku kubangelwa ukukhutshwa kombane ophezulu kumda we-strip.

Amanyathelo othintelo kwiziphene zangaphambi kwe-arc:

1. I-angle emile okwe-V ilawulwa ngokungqongqo ngaphakathi kwe-4 ~ 6
2. Umphetho we-strip ucocekile, ugudile kwaye awunayo i-burrs
3. Gcina amanzi okupholisa ecocekile, lawula indlela yokuhamba kwamanzi okupholisa, kwaye uzame ukunqanda i-engile engu-V.

Ukudibanisa okungonelanga

Esi siphene sibangelwa ukuba imiphetho yale micu mibini ishushu kodwa ayidityaniswanga ngokupheleleyo, kwaye i-weld entle ayiqulunqwanga.Isizathu esithe ngqo sokungonelanga kokudibanisa ubushushu obunganelanga ngexesha le-welding.Kukho izinto ezininzi ezinxulumeneyo ezikhokelela kubushushu obungonelanga be-welding, njengamandla aphezulu-frequency.Imveliso, i-angle ye-V kunye nobude bokufudumeza, indawo yebar yemagnethi, iimeko zokusebenza kunye nokupholisa kwebar yemagnethi, ubungakanani bekhoyili ye-induction, isantya se-welding, njl., ezi zinto zinempembelelo enye kwenye, kunye nesiphumo esidibeneyo. kukhokelela kwezo ziphene.

Amanyathelo othintelo kwiziphene ezingonelanga zokudityaniswa:

1. Ukutshatisa igalelo igalelo ubushushu kunye nesantya welding, iimpawu zemathiriyeli ekrwada umbhobho blank
2. Imeko yokusebenza yebha yamagnetic
3. I-angle ye-V kunye nobude bokufudumeza
4. Iinkcukacha zeekhoyili zokungeniswa

Ukuzinza kunye nemeko efanelekileyo yezixhobo ziimeko ezisisiseko zokuphepha iziphene.Ukufezekisa ukurekhoda kunye nohlalutyo lweeparamitha zenkqubo kunokunyusa umgangatho weepayipi.
